What kind of dyno? Inertial or brake? Will it use SAE correction? Will it adjust to sea level conditions? My guess is about the same if no corrections and an inertial dyno.

Now onto the soapbox. Dyno numbers are just guesses. Too many vairiables to treat them as any better than an educated guess. If you want better numbers, do about 5 quarter mile runs, weight the truck on certified scales, and apply the formula. Much more accurate than a dyno. The formula uses trap speed, not e.t., so reaction times are not considered, so that error source is out the window.
